" To all who mat may concern.

Be it known that I, GEORGE J. McDon- NELL, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in a Machine for Making Clothes Hangers, of which the following is a Specification.

. This inventionarelatesito a machine which performs the bending operation in the mak ing of a wire clothes; hanger. In particular it relates to certain improvements in the means for delivering individual wires in position to beoperated upon by the forming dies; to the construction of the dies themselves and other parts associated therewith; to the mechanism by which the dies are operated to produce the desired bends in the material which is worked upon; and, in

general, to the various features of construction andcombinations of parts which are -Fig. 4 is a nlan view lookin directl toward the bed plate of the machine;

Fig. 5 is a front elevation of the machine; Figs. 6 and 7 represent the several form-' ing ies together withthe operating mech- I anism therefor, initial and final positions being shown, respectively, in the two figures;

Fig. 8 is a longitudinal section through this1 bed'plate taken on-line 8-8 of Fig 9; an

' Fig. 9 is a transverse section therethrough taken approximately on line 99 of Fig. 8.

The present machine comprises a bed slate .A having, by preference,- a slight ownward inclination, as shown, the bed plate bei suitably supported as by a framework or egs B. Mounted upon the bed plate is a stationary die 10 which is in the general form of an isosceles triangle so arranged as'to present its base side toward the rear of the machine, its two shorter sides 11 and 12 being faced forwardly in consequence; Alsothere is mounted upon the bed plate forwardly of this triangular die and relatively close to its apex, a secondstat onary die 18, which is clrcular in formation. Operatively associated with these two dies are a pair of movable formin dies 14' and 15, each mounted fast upon t e upper end of shafts 16 and 17 respectively, wh1ch he to the rear of the triangular die in a line which parallelto the base side thereof.

The form of these two movable dies is such as to provide on each faces 18 and 19 adapted to bear squarely against the sides 11 and 12, respectively, of the triangular die when the movable dies have been swung to their extreme positions (see Fig. 7). In addition,

the die 14 is formed with a neck 20 connecting with a head 21 adapted to partlysurround the circular die 13, as indicated in Fig. 7. On the other movable die 15 is-an end face 22 extending away from its working face 19 at such an angle as to clear the head 21 of the companion die when the parts have reached the maximum position shown in the drawings.

- Each of the faces of the triangular die v$.50

is preferably grooved as at 23 (see Fig. 9) and likewise the working'faces of the movable dies may be similarly formed to better engage the wire which is being worked upon.

A wire of proper length, if placed adjacent the rear face of the triangulardie', lwill-ac c-c.- l

cordingly be acted upon by the movable dies to produce a generally triangular structureconforming to the shape of the die 10 with one wire end extended outwardly and thence curved in hook formatihn, as required by the contour of the head 21 in co-operation' with ,the circular die 13, so as to produce ,the airticle shown in Fig. 2. A small inclined block 245is shown in proximity to one side of the'triangular die for the purpose of holding one part of the hanger. thus. produced at a slight elevation above the bed plate, thus facilitating its removal therefrom withthe fingers. The free end of the hanger thus formed may be thereafter twisted around in the manner shown in Fig. 3 to produce a clothes hanger of conventional means he provided design. I Y

It is desirable that for deliveringwires, one at a time, in osition to be acted-u on by dies, of the 'nd described. With tin arranged certain mechanism which lies in part to the rear of the triangular die, and

in part thereover, as well as over the movable diesi This mechanism includes in' its 's end in view, I haveassembly a magazine extending lengthwise to the'diameter of the wires which are used in making the clothes hanger product. These walls may be conveniently secured at their ends by connecting plates 27 which have a mounting also on the bed plate so as to support the magazine at an elevatlon thereabove sufficient to afford clearance for the movements of the dies. The magazine which is thus formed is adapted to accommodate a plurality of wires C each cut to the desired length, and stacked one upon-theother. asbest indicated in Fig..

. support. for. the lowermost wire.

9. Wires of this kind maybesuppliedlto the machine from. any appropriate cutter (not shown) being delivered thereto with the aid of suitably inclined guides28, the outer ones of which are flanged at 29. as best shown in Figs. 4: and 5. In this manner. the wires are permitted to roll down the guides so as to drop into the magazine where they occupy the stacked relation described.

The lowermost wire in the magazine is maintained therein at an elevation somewhat higher than the movable dies with the aid of a plurality of spring arms 30each having an upper end 31 formed to connect with the corresponding edge-of the wall 26. At its lower end each spring arm is bent around in a forward direction, as at 32, to provide a Within the wall 26 are formed suitable recesses, one adjacent each' spring arm permitting the latter to swing t-hereinto, as required, with each release of the lowermost wire contained in th m agazing The means for effecting this release include$ai of bolts 33 each slidably mounted within a guidewer block 34 which is connected to the bed plate at a point rearwardly of the magazine. The forward end of each bolt may be beveled as at 35 to provide, in effect, duplex wedges the upper faces of which are disposed in a pane transverse to the magazine walls.

ithin these walls are formed registering openings 36 in the path of movement of the bolt -wedges p'ermitting'the latter to occupy either of the positions shown by the full and dotted lines in Fig. 9.' When moved to a forward position, the several wedges will displace from the magazine the lowermost wire, forcing the spring arms rearwardly for this purpose, each wedge at the same time being projected beneath the wire thereabove to afford support for all the wires in the magazine during the brief interval that the spring arms are retracted.

The two bolts which thus act to deliver the wires individually in position to be acted upon are operated in conjunction with-the The; meaififior accomplisha spring 37 connected to ing this includ a belt from any suitablesource.

.ofco-operation with the two stationary dies dies are ready to receive a new. Wire, the

rocker arms are engaged by the cam faces to exert a 'forward pressure on each of the two bolts 33 with the consequence that a wire is thereby displaced from the magazine to drop into operative position. upon the bed plate. lithnlommencement of oscillation of the two movable dies, the rocker arms shift their position with theTe?1Tt tlia t the--- bolts are then retracted, thus permitting the 85 entire stack of wires to descend in theanagazine a distance equal to the diameter of one wire. It will thus be noted that the mechanism described provides an automatic feed 'for the wires such as to deposit them individually, in position for forming with each operation of the dies.

The mechanism for oscillating the dies may be of any approved kind. As illustra-.

tive of a construction which will answer 95 the purpose of this invention, I have shown in Figs. 6 and 7 an arrangement of gears, two of which 45 and 46 are made fast to the shafts 16 and 17 respectively. A pitman 47 connects one of these gears with a third gear 48, .which latter is in mesh with a pinion 49 having connection with a pulley 50 to which power is supplied as by means of With rotation of the gear 48, the other two gears the pitman being suc' spastic the latter a range of movement of perhaps 135. In this manner, the movable dles are assured so as to perform upon the wire the bending operations theretofore ,described.

It will be apparent that'the machineof my invention may be embodied. in forms other than the one herein shown and described without sacrifice of the features of improvement herein set forth and claimed, and accordingly I desire that any such modifications shall be included within the scopeof this patent in so far as they respond to this invention as defined in the claims following.

I claim:
